Attachment device for attaching slinging or lashing means

ABSTRACT

Disclosed is an attaching device for attaching stopping or lashing means to objects that are to be transported or tied down, comprising a fixing element ( 1 ), an attaching element ( 16 ), and a connecting element ( 15 ) which is rotatably mounted on a socket ( 4 ) wrapped around the fixing element ( 1 ) and connects the attaching element ( 16 ) to the fixing element ( 1 ). The connecting element ( 15 ) leans against ring flanges ( 6, 7 ) placed at the ends of the socket ( 4 ) via series of rolling bodies ( 12, 13 ) so as to allow said connecting element ( 15 ) to rotate without jerking and make it sufficiently tilt-proof.

TECHNICAL FIELD

The invention relates to an attachment device for attaching slinging or lashing means to articles which are to be transported or lashed, having a fastening element which serves for fastening the same on the respective article and is formed by a bolt, having an attachment element for the slinging or lashing means, and having a connecting element which connects the fastening element to, the attachment element, is mounted, such that it can be rotated about the longitudinal axis of the fastening element, on a two-part bushing enclosing the fastening element over part of its length, and has its axial position on the bushing secured by annular flanges arranged at opposite ends of the bushing.

PRIOR ART

An attachment element of the abovementioned type is known from DE 10013845 A1. In the case of the known device, the connecting element is mounted with a sliding fit on a bushing which comprises two parts, of which the facing end surfaces butt against one another. The sliding mounting usually satisfies the requirements which are to be fulfilled. However, problems may arise if heavy articles are to be turned in addition to being raised. In order to increase the rotatability of a connecting element, it is known from DE 8406130.8 U1 to arrange, between the fastening element and the connecting element, a series of rolling-contact bodies with the rolling-contact bodies comprising balls which have to be introduced into their guide path from the outside of the connecting element with comparatively high outlay. The use of just one series of rolling-contact bodies places narrow limits on the tilting resistance of the connecting element in relation to the fastening element of this second known device. Finally, U.S. Pat. No. 3,371,951 A discloses an attachment device in the case of which the fastening element, which is formed by a bolt, is retained by two bushings which enclose the fastening element. In order to ensure the rotatability of the attachment element in the case of this device, the two bushings are supported, on the one hand, against the head of the bolt, which forms the fastening element, via an axial bearing comprising two bearing rings and balls, and, on the other hand, on the article which is to be provided with the attachment device, via a further axial bearing of the same design and an intermediate ring. The third known device is unsatisfactory insofar as it is of complicated construction and the rolling-contact bodies of its axial bearings are subjected to an uncontrolled level of prestressing which depends on the tightening torque of the bolt designed as the fastening element.

DESCRIPTION OF THE INVENTION

The object of the invention, in the case of an attachment device of the type in question, is to increase the relative movement capability between the fastening element and the connecting element by replacing the sliding mounting with an easy-to-install rolling-contact mounting, a high level of tilting resistance of the connecting element being desired at the same time. This object is achieved, in the case of an attachment device of generic type, in
